Lilacs equals spring to me. The variety of colors they come in are breathtaking and they make such great bouquets and decorations.

It is said that Purple lilac symbolizes "first emotions of love" in the language of flowers. (Wikipedia)

The story of lilac, according to Greek mythology, begins with a beautiful nymph named Syringa (lilac’s botanical name). Captivated by her beauty, Pan, the god of the forests and fields, chased Syringa through the forest. Frightened by Pan’s affections, Syringa escaped him by turning herself into an aromatic bush – the flower we now refer to as lilac. (teleflora.com)
